HATEBRAKE Muzzle Booster

A common problem in short barrel PDW’s with low-pressure cartridges is reliable cycling. Maxim Defense HATEBRAKE Muzzle Booster is designed to regulate firearm exhaust gases to ensure PDW’s cycle more reliably. The primary design features include the redirection of the sound signature, decreasing the flash signature, significantly reducing recoil, and increasing accuracy.

The HATE BRAKE installs with a 3/8” drive socket from the front, enabling it to be installed under a handguard without removing the handguard. During installation, the HATEBRAKE locks into place with K-Taper, a patent-pending taper locking technology, replacing the need for proprietary tapered barrels. The external shape of the HATEBRAKE is designed to work with M-Slot compatible hand guards. The HATEBRAKE starts at just $199.95.

M-RAX Rapid Attachment System

Unlike the traditional M-Slot mounting systems, M-RAX utilizes the full slot of your rail, maximizing space. This makes the M-RAX system end-to-end stackable, giving you the option to create seamless monolithic rail sections where needed. Installation and removal is a breeze. Thanks to the spring-loaded screws, the M-RAX system removes mounting frustrations. Simply push the screw in with a standard hex tool and rotate 90 degrees. The locking lugs engage that readily. No more fighting or timing screws. Offered in 2, 3, 4, 5 and 6 M-Slot lengths, the M-RAX is shipping today and starts at an MSRP of $39.95.
